# What is the Full Form of ALU?

The full form of ALU is Arithmetic Logic Unit. The ALU is a sort of digital circuit used in computer science to perform various operations on binary values. The ALU primarily conducts arithmetic operations and bitwise operations. The ALU circuit is utilised in the production of many computer-based devices such as CPUs, FPUs, and GPUs.

Input is how operations are done, and in ALU, input is referred to as operands. In addition, the output is the ultimate result achieved after performing all procedures. Both input and output remain between the external status registers and the Arithmetic Logic Unit circuit.

## Applications of ALU

Arithmetic Logic Unit ALU helps in the execution of numerous logical applications in CPUs and other computer systems. They are as follows:

## Complex Operations in ALU

ALU is designed to perform a variety of sophisticated computer science functions. However, some undesirable factors, such as high complexity, large size, and high power consumption, can impede complex functions. As a result, ALU is restricted to simple functions.

The external processor circuitry is used to solve this problem. These processors perform several complex functions by organising the values of operations.

## Multiple Precision Arithmetic in ALU

Multiple-precision arithmetic is a sort of algorithm that is used to accomplish a variety of arithmetic operations. Multiple Precision Arithmetic algorithms operate on huge inputs with large word sizes as compared to ALU. The operands are organised according to size to aid this procedure. The operands can be placed in descending order from most-significant Input (MS) to least-significant Input (LS) and vice versa.

The Multiple-precision arithmetic operation operates directly with operand pieces, resulting in the same fragments.
